Mynes eucosmetos, n. sp. 



§ . Exp. 2v in. Alls stramineo-albis, costa anticarum et marginibus 

 externe nigris, margine ad apicem anticarum latiore et stramineo 

 atomato, basi et marginibus nigris introrsum glauco tinctis. 

 Subtus anticis basi, apice ipso, costa, et fascia arcuata, a costa ad 

 angulum analern eunte, nigris; area discali et area subapicali albis, 

 hac jiavo tincta, macula ovali rufa in medio fascice nigra mar- 

 ginem externum versus notata : posticis Icete Jiavis nigro circum- 

 cinctis, introrsum vivide Jiavis et fascia arcuata limbo externo sub- 

 paralleli notatis, linea angusta alba in Umbo anali ipso, costa ad 

 basin rufa, macula juxta earn, et altera angulum analern versus 

 nigris notatis. 

 This appears to be a very distiuct insect : it differs from all the 



other described species in the extreme brilliancy of the markings of 



the underside. 



Pieris bagoe, Boisd. Voy. Astr. Lep. p. 49. 



Pieris eurygania, Godm. & Salv. P. Z. S. 187S, p. 734, and 1879, 

 p. 159, t. 15. f. 5, 6. 



Boisduval described a female Pieris in the Voyage of the ' Astro- 

 labe ' under this name, giving as its habitat " Port Praslin (Nouvelle- 

 Hollande)," an evident mistake for " Nouvelle-Irelande." We think 

 it undoubtedly the same as our P. eurygania, of both sexes of which 

 we gave figures in our last paper. 



Callidryas catilla (Cram.). 



A female of this widely ranging species from the Duke-of-York 

 group of islands. 



Papilio cilix, n. sp. 



$ . Exp. 5*6 in. P. albino similis, sed major et posticarum litura 

 straminea aream medium occupante multo augustiore et ad limbum 

 internum producta, margine ejus extrorsum inter venas convexo, in- 

 trorsum fere in linea recta ducto ; macula ochraceo-rufa angulum 

 analern versus, altera ultra earn minore notata : subtus posticis 

 maculis septem albis in serie transeuntibus, quarum prima et ultima 

 lunulatae sunt, aliis quinque subrotundis, lunulis quoque septem sub- 

 marginalibus (ultima in finem marginis interni posita) ochraceo- 

 rufis, lunulisque cyaneis, inter ioribus fere obsoletis; caudis majoribus 

 et latioribus. 

 2 mari similis, sed saturatior et litura posticarum latiore. 

 In a former paper (P. Z. S. 1877, p. 148), we mentioned having 

 received from Mr. Brown two imperfect specimens of a Papilio 

 allied to P. albinus, which we thought might prove to be a distiuct 

 species. In the present collection there are more examples of this 

 insect, which confirm this opinion ; and we have therefore given it a 

 specific name. 



It differs from P. albinus in several important points : the posterior 

 wings are more elongated, and the tails longer and broader ; the
